Soon after his return from Europe he was admitted to the bar in his native State, where he continued to practise till 1813. At that period, feeling the want of a wider field in which to exercise his talents, he determined, having previously married his cousin, the daughter of Dr. Wheaton of Providence, to remove to New-York with his wife. We must not omit to mention, that before leaving Providence he pronounced a Fourth of July Oration, in which he spoke with generous indignation of the bloody wars which then distracted Europe, and the disastrous consequences of which his residence in France had given him an opportunity to observe. But although thus warmly opposed to wars of conquest, there were cases in which he deemed resistance a sacred duty; he therefore zealously devoted his pen to encouraging his fellow-countrymen in resisting the unjust encroachments of England. During two years he edited the National Advocate, and the spirit as well as the fairness with which its leading articles were written, insured the success of the paper, and established his reputation in New-York. At the same time he held the office of Justice of the Marine Court, and for a few months that also of Army Judge Advocate. In 1815 he returned to the practice of his profession, and published in the same year a Treatise on the Law of Maritime Captures and Prizes, which Mr. Reddie of Edinburgh has since pronounced to have been the best work then published on the subject; no small praise, if we consider that Mr. Wheaton was only thirty years of age at the time it was written. In 1816 he was named Reporter of the Supreme Court at Washington, and continued to hold this place until 1827. The Reports, of which he published a volume yearly, and which were highly esteemed by American lawyers, were abridged without his consent soon after he went abroad. The publication of this abridgment occasioned a lawsuit, which ended only with his life. The following letter, for which we are indebted to the kindness of Professor Parsons, of the Law-school in Cambridge, will, we think, be read with interest. We must only remark, that it is an error to suppose that Mr. Wheaton shunned general society after he went to Europe; he joined in it, on the contrary, more than is usual to men of his age in our country. Cambridge, May 22, 1853. "I am very glad to offer even a slight contribution to this memorial, of one so worthy of all respect as the late Mr. Wheaton. And you must permit me to express the hope that the sketch you now propose to make, will hereafter be expanded into that history of his life and exhibition of his character, which should be given to the world, in justice to him and to the very many to whom it would be most acceptable. I can speak of him from personal acquaintance, only after a long interval, when even recollections so pleasant as those of my intercourse with him have become somewhat dim.
